Hello Snapcraft community,

I would like to create a package for Eclipse Papyrus.

But I get this error when building:

[e[1;34mINFOe[m] Computing target platform for MavenProject: org.eclipse.papyrus:org.eclipse.papyrus.rcp:5.2.0-SNAPSHOT @ /build/eclipse-papyrus-snapcraft/parts/eclipse-papyrus-snapcraft/build/releng/rcp/org.eclipse.papyrus.rcp/pom.xml

Failed to run 'override-build': Exit code was 1.

So I tested on Github Action and I don’t have an error when I compile. There is a small difference between Snapcraft.io and Github Action, which is that the former has the proxy, while the latter does not. To compile Eclipse Papyrus I use Maven and Java 11. Knowing that Java 11 is the minimum version for Eclipse Papyrus.

Here’s the difference between the Snapcraft.io version and the Github Action version.

Here is the Snapcraft.io version: snapcraft.yaml

override-build: |
    git checkout "5.2.0" -b latest
    snapcraftctl set-version "$(git describe --tags | sed 's/v//' | sed "s/-g/%/"  | cut -d "%" -f1)"
    # Gets the host and port from a proxy URL
    #   $1 = the proxy URL, such as "http://10.10.10.1:8222/"
    getproxy () {
        host=$(echo "$1" | sed -E 's|https?://([^:/]*):?[0-9]*/?|\1|')
        port=$(echo "$1" | sed -E 's|https?://[^:/]*:?([0-9]*)/?|\1|')
    }
    # Sets Java networking properties when using a proxy server
    if [ -n "${http_proxy:-}" ]; then
        getproxy "$http_proxy"
        http="-Dhttp.proxyHost=$host -Dhttp.proxyPort=$port"
    fi
    if [ -n "${https_proxy:-}" ]; then
        getproxy "$https_proxy"
        https="-Dhttps.proxyHost=$host -Dhttps.proxyPort=$port"
    fi
    # Builds Maven
    export MAVEN_OPTS="$http $https"
    mvn -f $SNAPCRAFT_PART_BUILD/releng/rcp/pom.xml -Dpapyrus.repo.main=https://download.eclipse.org/modeling/mdt/papyrus/updates/releases/2021-12/6.0.0/main/ clean verify
    tar -xf "${SNAPCRAFT_PART_BUILD}/releng/rcp/org.eclipse.papyrus.rcp.product/target/products/org.eclipse.papyrus.rcp.product-linux.gtk.x86_64.tar.gz" -C "${SNAPCRAFT_PART_INSTALL}"

Here’s the Github Action version: snapcraft.yaml

override-build: |
    git checkout "5.2.0" -b latest
    snapcraftctl set-version "$(git describe --tags | sed 's/v//' | sed "s/-g/%/"  | cut -d "%" -f1)"
    mvn -f $SNAPCRAFT_PART_BUILD/releng/rcp/pom.xml -Dpapyrus.repo.main=https://download.eclipse.org/modeling/mdt/papyrus/updates/releases/2021-12/6.0.0/main/ clean verify
    tar -xf "${SNAPCRAFT_PART_BUILD}/releng/rcp/org.eclipse.papyrus.rcp.product/target/products/org.eclipse.papyrus.rcp.product-linux.gtk.x86_64.tar.gz" -C "${SNAPCRAFT_PART_INSTALL}"

Here are the logs of the Snapcraft.io version: launchpad.net

Here are the logs of the Github Action version: github.com

Here is the repository of Eclipse Papyrus: org.eclipse.papyrus.git - modeling.mdt.papyrus project repository

Thank you for your help.

Great regards
